9.4 Implicatures and the semantics/pragmatics boundary
• Semantic meaning:
is the meaning that is associated with the words themselves,
independent of context.
• Pragmatic meaning:
is the meaning which arises from the context of the utterance.

9.4 Implicatures and the semantics/pragmatics boundary
Truth conditions of a sentence
depend only on the
“semantic content” or sentence meaning,
and not on
pragmatic meaning
“Truth conditional meaning” “sentence meaning”

The conventional implicatures of words like but and therefore
conventional meaning
conventional meaning is not always truth-conditional

Generalized conversational implicatures
the sequential ‘and then’ use of and

9.4 Implicatures and the semantics/pragmatics boundary
Examples like
a. If the old king has died of a heart attack and a republic has been
declared, then Tom will be quite content.
b. If a republic has been declared and the old king has died of a heart
attack, then Tom will be quite content.

‘If he had three beers and drove home, he broke the law;
but if he drove home and had three beers, he did not break the law’.

9.4 Implicatures and the semantics/pragmatics boundary
• Proponents of the Relevance Theory argue that
the sequential ‘and then’ use of and is an explicature.
• A similar analysis is proposed for most if not all of the
inferences that Grice and the “neo-Griceans” have identified as
generalized conversational implicatures: within Relevance Theory
they are generally treated as explicatures.

9.4 Implicatures and the semantics/pragmatics boundary
Mr. Dumas: “This changes everything”
“You of course have the originals?”
Mr. Quintanilla: “Not all of them”
not none

9.4 Implicatures and the semantics/pragmatics boundary
Generalized conversational implicatures can be used
to communicate false information, even when the
literal meaning of the sentence is true.

9.4.1 Why numeral words are special
Scalar implicatures
cardinal numbers
Horn (2004) uses the following examples to bring out
this difference
16. (Kroeger, 2019)
9.4.1 Why numeral words are special
Scalar implicatures
(1)
A: Did many of the guests leave?
B1: ?No, all of them.
B2: Yes, (in fact) all of them.
On the scale:
< none, some, many, all >
stronger
(more informative)
entails ‘(at least) many’
and implicates ‘not all’

9.4.1 Why numeral words are special
Scalar implicatures
(2)
A: Do you have two children?
B1: No, three.
B2: ?Yes, (in fact) three.
entails ‘(at least) two’
and implicates ‘not more than’
Numerals like two allow two
distinct readings:
‘at least 2’ vs ‘exactly 2’
neither of these is derived as
an implicature from the other.
18. entails ‘(at least) two’
implicates ‘not more than’
(Kroeger, 2019)
9.4.1 Why numeral words are special
Scalar implicatures
(3)
a. Neither of us has three kids —
she has two and I have four.
b. # Neither of us liked the movie —
she adored it and I hated it.
‘exactly three’
on the scale
<hate, dislike, neutral, like, love/adore>

9.4.1 Why numeral words are special
Horn (1992) notes several other properties which set
numerals apart from other scalar terms, and which
demonstrate the two distinct readings for numerals:
20. (Kroeger, 2019)
9.4.1 Why numeral words are special
Property 1
Mathematical statements
do not allow “at least” readings,
2 + 2 + 3
(should be true under “at least 3”
reading)
Also, round numbers are more
likely to allow “at least” readings
than very precise numbers
I have $200 in my bank account, if
not more.
I have $201.37 in my bank account,
#if not more.

9.4.1 Why numeral words are special
Property 2
Numerical scales are potentially reversible depending on the context
a. You can survive on 2000 calories per day (or more).
b. You can lose weight on 2000 calories per day (or less).
22. (Kroeger, 2019)
9.4.1 Why numeral words are special
Property 3
The “at least” interpretation is only possible with the distributive
reading of numerals, not the collective reading
a. Four salesmen have called me today, if not more.
b. Four students carried this sofa upstairs for me, #if not more.
23. (Kroeger, 2019)
9.4.1 Why numeral words are special
Property 4
The “at least” interpretation is disfavored when a numeral is
the focus of a question
Q: Do you have two children?
A1: No, three.
A2: ?Yes, in fact three.

9.5 Conclusion
• The boundary between semantics and pragmatics is not tenable.
• Pragmatic inferences do contribute to truth-conditional content.
• Truth-conditional content is almost the same thing as conventional meaning.
• (At least) generalized conversational implicatures affect truth-conditions
• Other types of pragmatic inferences, which we refer to as explicatures,
are needed in order to determine the truth value of a sentence.
